What You Need To Know...
MAFS.912.G-SQR.1.1 - Know the properties of dilations given by a center and a scale factor.
- A dilation taking a line not passing through the center of the dilation to a parallel line and leaves a line passing through the center unchanged.
- The dilation of a line segment is longer or shorter in the ratio given by the scale factor.
- The benchmark will be assessed using Equation Response, Multi-select, Graphic Response, Open Response, Selectable Text, or Simulation Response.
- Items may use line segments of a geometric figure.
- Items will give the center of dilation and the scale factor.
- Items may give the student a figure or its dilation, center, and scale and then ask the student to verify the properties of dilation.
Example One
Example Two
Write the coordinates of the vertices after a dilation with a scale factor of 5, centered at the origin.
